Introduction For our ECE 4760 final project, we implemented an interactive CPR training dummy which can coach the trainees through the CPR process with a LCD to display instructions. The prototype CPR training dummy built is a budget-friendly one that contains a re-programmable Atmel ATmega1284 microcontroller and other hardware components so that it can interact […]

Introduction For our final project, we have decided to use the microcontroller provided to make a device which would measure body fat percentage of one’s body. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine

we designed and implemented a speaker recognition device that acts as a lock triggered by the sound of your voice saying a specific passcode. The implementation uses hardware filtering from a microphone and many signal processing concepts in software. All software and matching is implemented in the ATmega1284p. The lock has two modes: training and
Introduction Musical Instrument Digital Interface, or MIDI, is a standard that describes a protocol, digital interface and specific physical connections that allow electronic music devices and computers to communicate with each other. For our final project, we created a MIDI glove that is capable of connecting to a virtual synthesizer on our computer and controlling

Introduction “A resistive touch screen robot that follows a user-defined path input by drawing on the touch screen.”” We designed and implemented a robot that follows the path drawn on a touchscreen. The touchscreen is mounted on top of the robot, and once the path is drawn, and the user picks up their finger, the
SingLock is a pitch-based security system based on ATMEL MEGA1284P microcontroller featuring two password protection stages: one based on a 4-digit numeric personal identification number inputted via the keypad and another based on two pitches inputted via the microphone. Most security systems we find today are keypad and/or keyboard-based. Speech, rather than button-pressing and/or typing,
Introduction The Skittles Mini-Factory is self-contained repackaging unit that separates Skittles by color. Once separated, the Skittles are resealed in individual plastic bags. The Skittles are dispensed one at a time (either automatically or manually) onto a light sensing module. Red, green, blue, and white light are reflected off the skittle and read by

Introduction Our final project was to create a rapid prototyping machine for electrical circuits by repurposing an old pen plotter that we fitted with an electrically conductive pen. Our plotter utilized an atmega 1284P to control the x and y-axis motors, and to raise and lower the pen. We created a web app that allowed

INTRODUCTION This project implements a real-time scrolling spectrogram-style visualization of an audio signal. We successfully displayed the frequency spectrum content in real time using a 4-bit grayscale scrolling display on any NTSC television. The frequency spectrum of an audio line-in input or mic input is calculated and displayed in real time using two ATmega1284 microcontrollers
